NEMIX RAM
A 96 GB DDR5-4800 registered ECC module with CL40 latency and 1.1 V operation for compatible server platforms
This 96GB DDR5 4800 registered DIMM adds ECC-protected capacity to compatible Hynix servers and workstations. The single 2Rx4 module operates at 1.10V with CL40 latency and fits 288-pin DDR5 RDIMM slots. IT teams choose it to expand memory in mission-critical systems that require registered, error-correcting modules.
The jump is worth it when workloads exceed the limits of smaller registered modules and the platform supports 96GB per slot. Registered signalling and on-die ECC maintain data integrity at this density, while the 4800 MT/s rate keeps bandwidth aligned with DDR5-4800 server platforms. Systems limited to lower maximum densities or non-registered memory cannot use this module.
The 96GB capacity provides headroom for dense VM hosting, in-memory analytics and multi-tenant containers on a single DIMM slot. Workloads that scale beyond 96GB per channel or require higher clock speeds than 4800 MT/s will need additional modules or a faster memory tier. The lack of a heat spreader means airflow must be managed by the chassis.

This module uses the standard 288-pin DDR5 RDIMM form factor. It fits server and workstation boards that accept registered DDR5 DIMMs.
Align the notch with the slot key, press firmly until both retention clips click. The step often missed is verifying the motherboard supports 2Rx4 registered ECC at 1.1 V.
DDR5 RDIMMs have no scheduled replacement interval. Replace only if memory diagnostics report uncorrectable ECC errors or the module fails to post.
